<div>(1) push_back( P )：在 S 后连接一个字符串 P，即 S = S + P，代价为| P |；</div>
<div>(2) push_front( P )：在 S 前连接一个字符串 P，即 S = P + S，代价为| P |；</div>
<div>(3) symmetry_back( )：将 S 翻转后连接在 S 之后，即 S = S + rev(S)，代价为 1；</div>
<div>(4) symmetry_front( )：将 S 翻转后连接在 S 之前，即 S = rev(S) + S，代价为 1；</div>
<div>给定一个目标串 S，要求你通过上述四种操作，用最少的代价合成出目标串。初始只有一个空串。</div>
